Microfilaruria by Dirofilária immitis in a dog in the city of Uberlândia - Minas Gerais
Abstract. Heartworm is considered an important public health problem, as its main vector is domestic dogs, there is great proximity of these dogs with their owners, which can generate a possible cross-transmission. Therefore, it is necessary that health professionals are attentive and trained in clinical and laboratory identification, in order not to neglect it. The objective is to describe the case of Dirofilaria immitis in a dog in the city of Uberlândia - MG, where the microfilaria larvae were initially found by a urine examination in the sedimentcopic phase and direct blood microscopy. Laboratory tests performed: complete blood count, thick drop, biochemical, urinalysis. Several changes were present in the urine test, hematuria, pyuria, hyperbilirubinemia, proteinuria, and the presence of microfilaria, other changes such as azotemia, hematological parameters that indicate severe anemia, leukocytosis, neutrophilia, and lymphocytosis. There are few case reports in which microfilariae were found in the examination of urine in dogs. This report assists in decision making and more accurate clinical diagnosis and points to previously unknown ways of laboratory investigation.
